SPRINGFIELD — An intentionally set fire at 119-121 Maynard Street on Thursday night caused $80,000 damage to the two-family home and another $10,000 damage to the exterior of the house next door, officials said.

A second floor tenant of 119-121 Maynard, identified as Michelle Kotarski, 38, was arrested at the scene and charged with arson of a dwelling, according to Dennis Leger, aide to Fire Commissioner Joseph Conant.

Kotarski was being treated at Baystate Medical Center for what were described as burns to her hands, said Springfield Police Capt. Cheryl C. Clapprood.

The fire began on the front porch and spread up the exterior of the 2½-story woodframe structure. It found its way into the attic and eventually burned through the roof.

The fire was reported just after 8 p.m., and the first firefighters arriving on scene within two minutes reported the front of the building was fully involved.

The exterior of the home was heavily damaged by flames, and firefighters had to cut through the roof and the exterior walls by the attic to get at remaining hot spots.

One firefighter was injured when he twisted his knee. He was taken to Baystate Medical Center for treatment, Leger said.

Tenants on the first floor were not home, and Leger said they were in the process of moving out.

According to city records, the property is owned by Lewis A. and Juliet Winston of Springfield. It has an assessed value of $92,000.

Maynard Street is located in the city’s Bay neighborhood, and runs between Acorn and State streets.
